  • Why would Mathematica break normal scoping rules in Module?

    - by Davorak
    As was pointed out in a recent post scoping does not work as expected inside of Module. An example from that thread is: Module[{expr}, expr = 2 z; f[z_] = expr; f[7]] (*2 z$1776*) But the following works as almost as expected. Module[{expr}, expr = 2 z; Set@@{f[z_], expr}; f[7]] (*14*) What language design consideration made wolfram choose this functionality?

  • How do I add a custom table to a form in another module in Drupal?

    - by Kareed
    I am trying to make a module to add a table to a form in another module. I found I can add the new data in a module_form_alter hook but how to I get it to run through a theme hook? The module I am trying to modify has a theme hook for the page I want to modify. I don't want to change the original form I just want to add a table with new data below it. Thanks

  • How do I use saz-sudo puppet module to deploy my own sudoers file with hiera?

    - by mr.zog
    I have saz-sudo installed and have created a site_sudo module based (I hope) on it. Here's what I have in my site_sudo/manifest/init.pp file: class { 'site_sudo': } sudo::conf { 'web': source => 'puppet:///files/etc/sudoers', } sudo::conf { 'syseng': priority => 10, content => "%sysadm ALL=(ALL) NOPASSWD: ALL", } include sudo No matter what I do, the sudoers file on the target is always overwritten with the sudoers.rhel6 file from saz-sudo module. I'm using common.yaml too: classes: - site_sudo

  • How to use DI and DI containers

    - by Pinetree
    I am building a small PHP mvc framework (yes, yet another one), mostly for learning purposes, and I am trying to do it the right way, so I'd like to use a DI container, but I am not asking which one to use but rather how to use one. Without going into too much detail, the mvc is divided into modules which have controllers which render views for actions. This is how a request is processed: a Main object instantiates a Request object, and a Router, and injects the Request into the Router to figure out which module was called. then it instantiates the Module object and sends the Request to that the Module creates a ModuleRouter and sends the Request to figure out the controller and action it then creates the Controller and the ViewRenderer, and injects the ViewRenderer into the Controller (so that the controller can send data to the view) the ViewRenderer needs to know which module, controller and action were called to figure out the path to the view scripts, so the Module has to figure out this and inject it to the ViewRenderer the Module then calls the action method on the controller and calls the render method on the ViewRenderer For now, I do not have any DI container set up, but what I do have are a bunch of initX() methods that create the required component if it is not already there. For instance, the Module has the initViewRenderer() method. These init methods get called right before that component is needed, not before, and if the component was already set it will not initialize it. This allows for the components to be switched, but it does not require manually setting them if they are not there. Now, I'd like to do this by implementing a DI container, but still keep the manual configuration to a bare minimum, so if the directory structure and naming convention is followed, everything should work, without even touching the config. If I use the DI container, do I then inject it into everything (the container would inject itself when creating a component), so that other components can use it? When do I register components with the DI? Can a component register other components with the DI during run-time? Do I create a 'common' config and use that? How do I then figure out on the fly which components I need and how they need to be set up? If Main uses Router which uses Request, Main then needs to use the container to get Module (or does the module need to be found and set beforehand? How?) Module uses Router but needs to figure out the settings for the ViewRenderer and the Controller on the fly, not in advance, so my DI container can't be setting those on the Module before the module figures out the controller and action... What if the controller needs some other service? Do I inject the container into every controller? If I start doing that, I might just inject it into everything... Basically I am looking for the best practices when dealing with stuff like this. I know what DI is and what DI containers do, but I am looking for guidance to using them in real life, and not some isolated examples on the net. Sorry for the lengthy post and many thanks in advance.

  • Why does Saxon evaluate the result-document URI to be the same?

    - by Jan
    My XSL source document looks like this <Topology> <Environment> <Id>test</Id> <Machines> <Machine> <Id>machine1</Id> <modules> <module>m1</module> <module>m2</module> </modules> </Machine> </Machines> </Environment> <Environment> <Id>production</Id> <Machines> <Machine> <Id>machine1</Id> <modules> <module>m1</module> <module>m2</module> </modules> </Machine> <Machine> <Id>machine2</Id> <modules> <module>m3</module> <module>m4</module> </modules> </Machine> </Machines> </Environment> </Topology> I want to create one result-document per machine, so I use the following stylesheet giving modelDir as path for the result-documents as parameter. <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" name="myXML" doctype-system="http://java.sun.com/dtd/properties.dtd"/> <xsl:template match="/"> <xsl:for-each-group select="/Topology/Environment/Machines/Machine" group-by="Id"> <xsl:variable name="machine" select="Id"/> <xsl:variable name="filename" select="concat($modelDir,$machine,'.xml')" /> <xsl:message terminate="no">Writing machine description to <xsl:value-of select="$filename"/></xsl:message> <xsl:result-document href="$filename" format="myXML"> <xsl:variable name="currentMachine" select="Id"/> <xsl:for-each select="current-group()/LogicalHosts/LogicalHost"> <xsl:variable name="environment" select="normalize-space(../../../../Id)"/> <xsl:message terminate="no">Module <xsl:value-of select="."/> for <xsl:value-of select="$environment"/></xsl:message> </xsl:for-each> </xsl:result-document> </xsl:for-each-group> </xsl:template> As my messages show me this seems to work fine - if saxon would not evaluate the URI of the result-document to be the same and thus give the following output. Writing machine description to target/build/model/m1.xml Module m1 for test Module m2 for test Module m1 for production Module m2 for production Writing machine description to target/build/model/m2.xml Error at xsl:result-document on line 29 of file:/C:/Projekte/.../machine.xsl: XTDE1490: Cannot write more than one result document to the same URI, or write to a URI that has been read: file:/C:/Projekte/.../$filename file:/C:/Projekte/.../machine.xsl(29,-1) : here Cannot write more than one result document to the same URI, or write to a URI that has been read: file:/C:/Projekte/.../$filename ; SystemID: file:/C:/Projekte/.../machine.xsl; Line#: 29; Column#: -1 net.sf.saxon.trans.DynamicError: Cannot write more than one result document to the same URI, or write to a URI that has been read: file:/C:/Projekte/.../$filename at net.sf.saxon.instruct.ResultDocument.processLeavingTail(ResultDocument.java:300) at net.sf.saxon.instruct.Block.processLeavingTail(Block.java:365) at net.sf.saxon.instruct.Instruction.process(Instruction.java:91) Any ideas on how to solve this?

  • Caveats with the runAllManagedModulesForAllRequests in IIS 7/8

    - by Rick Strahl
    One of the nice enhancements in IIS 7 (and now 8) is the ability to be able to intercept non-managed - ie. non ASP.NET served - requests from within ASP.NET managed modules. This opened up a ton of new functionality that could be applied across non-managed content using .NET code. I thought I had a pretty good handle on how IIS 7's Integrated mode pipeline works, but when I put together some samples last tonight I realized that the way that managed and unmanaged requests fire into the pipeline is downright confusing especially when it comes to the runAllManagedModulesForAllRequests attribute. There are a number of settings that can affect whether a managed module receives non-ASP.NET content requests such as static files or requests from other frameworks like PHP or ASP classic, and this is topic of this blog post. Native and Managed Modules The integrated mode IIS pipeline for IIS 7 and later - as the name suggests - allows for integration of ASP.NET pipeline events in the IIS request pipeline. Natively IIS runs unmanaged code and there are a host of native mode modules that handle the core behavior of IIS. If you set up a new IIS site or application without managed code support only the native modules are supported and fired without any interaction between native and managed code. If you use the Integrated pipeline with managed code enabled however things get a little more confusing as there both native modules and .NET managed modules can fire against the same IIS request. If you open up the IIS Modules dialog you see both managed and unmanaged modules. Unmanaged modules point at physical files on disk, while unmanaged modules point at .NET types and files referenced from the GAC or the current project's BIN folder. Both native and managed modules can co-exist and execute side by side and on the same request. When running in IIS 7 the IIS pipeline actually instantiates a the ASP.NET  runtime (via the System.Web.PipelineRuntime class) which unlike the core HttpRuntime classes in ASP.NET receives notification callbacks when IIS integrated mode events fire. The IIS pipeline is smart enough to detect whether managed handlers are attached and if they're none these notifications don't fire, improving performance. The good news about all of this for .NET devs is that ASP.NET style modules can be used for just about every kind of IIS request. All you need to do is create a new Web Application and enable ASP.NET on it, and then attach managed handlers. Handlers can look at ASP.NET content (ie. ASPX pages, MVC, WebAPI etc. requests) as well as non-ASP.NET content including static content like HTML files, images, javascript and css resources etc. It's very cool that this capability has been surfaced. However, with that functionality comes a lot of responsibility. Because every request passes through the ASP.NET pipeline if managed modules (or handlers) are attached there are possible performance implications that come with it. Running through the ASP.NET pipeline does add some overhead. ASP.NET and Your Own Modules When you create a new ASP.NET project typically the Visual Studio templates create the modules section like this: <system.webServer> <validation validateIntegratedModeConfiguration="false" /> <modules runAllManagedModulesForAllRequests="true" > </modules> </system.webServer> Specifically the interesting thing about this is the runAllManagedModulesForAllRequest="true" flag, which seems to indicate that it controls whether any registered modules always run, even when the value is set to false. Realistically though this flag does not control whether managed code is fired for all requests or not. Rather it is an override for the preCondition flag on a particular handler. With the flag set to the default true setting, you can assume that pretty much every IIS request you receive ends up firing through your ASP.NET module pipeline and every module you have configured is accessed even by non-managed requests like static files. In other words, your module will have to handle all requests. Now so far so obvious. What's not quite so obvious is what happens when you set the runAllManagedModulesForAllRequest="false". You probably would expect that immediately the non-ASP.NET requests no longer get funnelled through the ASP.NET Module pipeline. But that's not what actually happens. For example, if I create a module like this:<add name="SharewareModule" type="HowAspNetWorks.SharewareMessageModule" /> by default it will fire against ALL requests regardless of the runAllManagedModulesForAllRequests flag. Even if the value runAllManagedModulesForAllRequests="false", the module is fired. Not quite expected. So what is the runAllManagedModulesForAllRequests really good for? It's essentially an override for managedHandler preCondition. If I declare my handler in web.config like this:<add name="SharewareModule" type="HowAspNetWorks.SharewareMessageModule" preCondition="managedHandler" /> and the runAllManagedModulesForAllRequests="false" my module only fires against managed requests. If I switch the flag to true, now my module ends up handling all IIS requests that are passed through from IIS. The moral of the story here is that if you intend to only look at ASP.NET content, you should always set the preCondition="managedHandler" attribute to ensure that only managed requests are fired on this module. But even if you do this, realize that runAllManagedModulesForAllRequests="true" can override this setting. runAllManagedModulesForAllRequests and Http Application Events Another place the runAllManagedModulesForAllRequest attribute affects is the Global Http Application object (typically in global.asax) and the Application_XXXX events that you can hook up there. So while the events there are dynamically hooked up to the application class, they basically behave as if they were set with the preCodition="managedHandler" configuration switch. The end result is that if you have runAllManagedModulesForAllRequests="true" you'll see every Http request passed through the Application_XXXX events, and you only see ASP.NET requests with the flag set to "false". What's all that mean? Configuring an application to handle requests for both ASP.NET and other content requests can be tricky especially if you need to mix modules that might require both. Couple of things are important to remember. If your module doesn't need to look at every request, by all means set a preCondition="managedHandler" on it. This will at least allow it to respond to the runAllManagedModulesForAllRequests="false" flag and then only process ASP.NET requests. Look really carefully to see whether you actually need runAllManagedModulesForAllRequests="true" in your applications as set by the default new project templates in Visual Studio. Part of the reason, this is the default because it was required for the initial versions of IIS 7 and ASP.NET 2 in order to handle MVC extensionless URLs. However, if you are running IIS 7 or later and .NET 4.0 you can use the ExtensionlessUrlHandler instead to allow you MVC functionality without requiring runAllManagedModulesForAllRequests="true": <handlers> <remove name="ExtensionlessUrlHandler-Integrated-4.0" /> <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" /> </handlers> Oddly this is the default for Visual Studio 2012 MVC template apps, so I'm not sure why the default template still adds runAllManagedModulesForAllRequests="true" is - it should be enabled only if there's a specific need to access non ASP.NET requests. As a side note, it's interesting that when you access a static HTML resource, you can actually write into the Response object and get the output to show, which is trippy. I haven't looked closely to see how this works - whether ASP.NET just fires directly into the native output stream or whether the static requests are re-routed directly through the ASP.NET pipeline once a managed code module is detected. This doesn't work for all non ASP.NET resources - for example, I can't do the same with ASP classic requests, but it makes for an interesting demo when injecting HTML content into a static HTML page :-) Note that on the original Windows Server 2008 and Vista (IIS 7.0) you might need a HotFix in order for ExtensionLessUrlHandler to work properly for MVC projects. On my live server I needed it (about 6 months ago), but others have observed that the latest service updates have integrated this functionality and the hotfix is not required. On IIS 7.5 and later I've not needed any patches for things to just work. Plan for non-ASP.NET Requests It's important to remember that if you write a .NET Module to run on IIS 7, there's no way for you to prevent non-ASP.NET requests from hitting your module. So make sure you plan to support requests to extensionless URLs, to static resources like files. Luckily ASP.NET creates a full Request and full Response object for you for non ASP.NET content. So even for static files and even for ASP classic for example, you can look at Request.FilePath or Request.ContentType (in post handler pipeline events) to determine what content you are dealing with. As always with Module design make sure you check for the conditions in your code that make the module applicable and if a filter fails immediately exit - minimize the code that runs if your module doesn't need to process the request.© Rick Strahl, West Wind Technologies, 2005-2012Posted in IIS7   ASP.NET   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • How could there still not be a mysqldb module for Python 3? [closed]

    - by itsadok
    This SO question is now more than two years old. MySQL is an incredibly popular database engine, Python is an incredibly popular programming language, and Python 3 has been officially released two years ago, and was available even before that. What's more, the whole mysqldb module is just a layer translating Python's db-api to MySQL's API. It's not that big of a library. I must be missing something here. How come almost* nobody in the entire open source community has spent the (I'm guessing) two weeks it takes to port this lib? Is Python 3 that unpopular? Is the combination of python and mysql not as common as I assume? Or maybe it's just a lot harder to port mysqldb than I assume? Anyone know the inside story on this? * Now I see that this guy has done it, which takes some of the wind out of my question, but it still seems to little and too late to make sense. EDIT: OK, I'm aware that the stock answers for these kind of questions cover this one as well. Patches welcome, scratch your itch, we don't work for you and we don't have the time, etc. I actually took a shot at porting this about a year ago, but it was my first time doing anything with Python C extensions, and I failed. My point in writing this was not a plea for somebody to write it, but genuine curiosity: it seems that some much more complicated libraries have been ported to python 3 already, and in the poll for which libraries should be ported, mysqldb is not even nominated! That suggests that maybe (2) is the right answer. UPDATE: I found that there are several new libraries that provide mysql support under Python 3, I just wasn't googling hard enough. That explains everything.

  • Allow (and correct the URL) when there is a special character such as %26 using IIS and the rewrite module

    - by plumtreematt
    I'm struggling with a legacy app that uses special characters like %26 in the URL. The characters don't affect the app but can't be changed, so I'm trying to get IIS to deal with them. I've tried to ignore them using multiple methods, but nothing seems to work. So now I installed the IIS rewrite module and added a rewrite rule to web.config to replace the characters %26 with _, for example: <rewrite> <rules> <rule name="ampersand" patternSyntax="Wildcard" stopProcessing="true"> <match url="*%26*" /> <action type="Redirect" url="{R:1}_{R:2}" /> </rule> </rules> </rewrite> The problem is that IIS responds with "Bad Request" before the rewrite rule ever gets called. So my question is this: how can I change the order of precedence so that the mod rewrite filter will be called before IIS puts the ban hammer down on that URL?

The program works, but without any antialiasing, and I get these error messages: (I'm using ArchLinux) INFO:OpenGL.acceleratesupport:No OpenGL_accelerate module loaded: No module named OpenGL_accelerate INFO:OpenGL.formathandler:Unable to load registered array format handler numpy: Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/OpenGL/arrays/formathandler.py", line 44, in loadPlugin plugin_class = entrypoint.load() File "/usr/lib/python2.6/site-packages/OpenGL/plugins.py", line 14, in load return importByName( self.import_path ) File "/usr/lib/python2.6/site-packages/OpenGL/plugins.py", line 28, in importByName module = __import__( ".".join(moduleName), {}, {}, moduleName) File "/usr/lib/python2.6/site-packages/OpenGL/arrays/numpymodule.py", line 11, in <module> raise ImportError( """No numpy module present: %s"""%(err)) ImportError: No numpy module present: No module named numpy INFO:OpenGL.formathandler:Unable to load registered array format handler numeric: Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/OpenGL/arrays/formathandler.py", line 44, in loadPlugin plugin_class = entrypoint.load() File "/usr/lib/python2.6/site-packages/OpenGL/plugins.py", line 14, in load return importByName( self.import_path ) File "/usr/lib/python2.6/site-packages/OpenGL/plugins.py", line 28, in importByName module = __import__( ".".join(moduleName), {}, {}, moduleName) File "/usr/lib/python2.6/site-packages/OpenGL/arrays/numeric.py", line 15, in <module> raise ImportError( """No Numeric module present: %s"""%(err)) ImportError: No Numeric module present: No module named Numeric However, when I look into my site-packages folder, I see those modules present there. I have a wxPython demo program that uses GLCanvas, and it works fine, without any errors. My program is quite similar to the GLCanvas demo, involving just translations, rotations, drawing quads and some basic lighting. What am I doing wrong here? (The code is over 200 lines, if necessary I'll edit this and put it here.)

  • Debugging OWB generated SAP ABAP code executed through RFC

    - by Anil Menon
    Within OWB if you need to execute ABAP code using RFC you will have to use the SAP Function Module RFC_ABAP_INSTALL_AND_RUN. This function module is specified during the creation of the SAP source location. Usually in a Production environment a copy of this function module is used due to security restrictions. When you execute the mapping by using this Function Module you can’t see the actual ABAP code that is passed on to the SAP system. In case you want to take a look at the code that will be executed on the SAP system you need to use a custom Function Module in SAP. The easiest way to do this is to make a copy of the Function Module RFC_ABAP_INSTALL_AND_RUN and call it say Z_TEST_FM. Then edit the code of the Function Module in SAP as below FUNCTION Z_TEST_FM . DATA: BEGIN OF listobj OCCURS 20. INCLUDE STRUCTURE abaplist. DATA: END OF listobj. DATA: begin_of_line(72). DATA: line_end_char(1). DATA: line_length type I. DATA: lin(72). loop at program. append program-line to WRITES. endloop. ENDFUNCTION. Within OWB edit the SAP Location and use Z_TEST_FM as the “Execution Function Module” instead of  RFC_ABAP_INSTALL_AND_RUN. Then register this location. The Mapping you want to debug will have to be deployed. After deployment you can right click the mapping and click on “Start”.   After clicking start the “Input Parameters” screen will be displayed. You can make changes here if you need to. Check that the parameter BACKGROUND is set to “TRUE”. After Clicking “OK” the log for the execution will be displayed. The execution of Mappings will always fail when you use the above function module. Clicking on the icon “I” (information) the ABAP code will be displayed.   The ABAP code displayed is the code that is passed through the Function Module. You can also find the code by going through the log files on the server which hosts the OWB repository. The logs will be located under <OWB_HOME>/owb/log. Patch #12951045 is recommended while using the SAP Connector with OWB 11.2.0.2. For recommended patches for other releases please check with Oracle Support at http://support.oracle.com

  • Chrome and Firefox not able to find some sites after Ubuntu's recent update?

  • Adding a mini admin to a webpage.

    - by DADU
    Hello Picture this: you are creating a little module that people can incorporate into their website easily, for example, a little contact form. It would consist of a PHP file that outputs some HTML, a Javascript file (ajax etc.), a CSS file and a CSS skin. Now the person who doesn't know much about coding wants to integrate it on a webpage (website/index.php). We could do this with three rules of code: <link rel="stylesheet" href="module/css/module.css" /> <script src="module/js/module.js"></script> <?php require_once 'module/module.php'; ?> There's no doubt this part is questionable, right? Now when we want to add an admin for this little module, there are two options: Accessing the admin via an extra URL like website/module/admin.php and after authentication, displaying a page where the person can do all the settings. The person then goes back to index.php to see the results. Enabling the admin via an extra URL like website/module/admin.php and after authentication, redirecting back to index.php. The person can now edit the module directly (HTML5 contenteditable) and see changes live, on the webpage where everybody else will see it when the person saves the changes. Option 2 has a couple of advantages: The person doesn't have to toggle between admin and index.php. The person can see directly how it's looking at the webpage it's integrated in. The person probably feels like the module is more part of the webpage/website. Of course option 2 has some disadvantages too: Not everything works well editing it inline. The person would need to have an HTML5 compliant browser. Probably some more I can't think of right now. Now I have a few concerns that's I can't seem to see a clear answer to. How would we let the person integrate the admin on their webpage? The admin files only need to be included in index.php if the person has choosen to edit the module via the url (website/module/admin.php). But how can we do this if we have a admin.css file that belongs in the head section, an admin.php file that goes into the body, and another admin.js file that's included at the end of the body? How would we know the file that admin.php needs to redirect back to, after authentication? index.php could be any webpage with any name. Any real life website/web apps examples using this principle are welcome too. If there's something unclear, I am glad to add additional info.

  • Mixing Forms and Token Authentication in a single ASP.NET Application (the Details)

    - by Your DisplayName here!
    The scenario described in my last post works because of the design around HTTP modules in ASP.NET. Authentication related modules (like Forms authentication and WIF WS-Fed/Sessions) typically subscribe to three events in the pipeline – AuthenticateRequest/PostAuthenticateRequest for pre-processing and EndRequest for post-processing (like making redirects to a login page). In the pre-processing stage it is the modules’ job to determine the identity of the client based on incoming HTTP details (like a header, cookie, form post) and set HttpContext.User and Thread.CurrentPrincipal. The actual page (in the ExecuteHandler event) “sees” the identity that the last module has set. So in our case there are three modules in effect: FormsAuthenticationModule (AuthenticateRequest, EndRequest) WSFederationAuthenticationModule (AuthenticateRequest, PostAuthenticateRequest, EndRequest) SessionAuthenticationModule (AuthenticateRequest, PostAuthenticateRequest) So let’s have a look at the different scenario we have when mixing Forms auth and WS-Federation. Anoymous request to unprotected resource This is the easiest case. Since there is no WIF session cookie or a FormsAuth cookie, these modules do nothing. The WSFed module creates an anonymous ClaimsPrincipal and calls the registered ClaimsAuthenticationManager (if any) to transform it. The result (by default an anonymous ClaimsPrincipal) gets set. Anonymous request to FormsAuth protected resource This is the scenario where an anonymous user tries to access a FormsAuth protected resource for the first time. The principal is anonymous and before the page gets rendered, the Authorize attribute kicks in. The attribute determines that the user needs authentication and therefor sets a 401 status code and ends the request. Now execution jumps to the EndRequest event, where the FormsAuth module takes over. The module then converts the 401 to a redirect (302) to the forms login page. If authentication is successful, the login page sets the FormsAuth cookie.   FormsAuth authenticated request to a FormsAuth protected resource Now a FormsAuth cookie is present, which gets validated by the FormsAuth module. This cookie gets turned into a GenericPrincipal/FormsIdentity combination. The WS-Fed module turns the principal into a ClaimsPrincipal and calls the registered ClaimsAuthenticationManager. The outcome of that gets set on the context. Anonymous request to STS protected resource This time the anonymous user tries to access an STS protected resource (a controller decorated with the RequireTokenAuthentication attribute). The attribute determines that the user needs STS authentication by checking the authentication type on the current principal. If this is not Federation, the redirect to the STS will be made. After successful authentication at the STS, the STS posts the token back to the application (using WS-Federation syntax). Postback from STS authentication After the postback, the WS-Fed module finds the token response and validates the contained token. If successful, the token gets transformed by the ClaimsAuthenticationManager, and the outcome is a) stored in a session cookie, and b) set on the context. STS authenticated request to an STS protected resource This time the WIF Session authentication module kicks in because it can find the previously issued session cookie. The module re-hydrates the ClaimsPrincipal from the cookie and sets it.     FormsAuth and STS authenticated request to a protected resource This is kind of an odd case – e.g. the user first authenticated using Forms and after that using the STS. This time the FormsAuth module does its work, and then afterwards the session module stomps over the context with the session principal. In other words, the STS identity wins.   What about roles? A common way to set roles in ASP.NET is to use the role manager feature. There is a corresponding HTTP module for that (RoleManagerModule) that handles PostAuthenticateRequest. Does this collide with the above combinations? No it doesn’t! When the WS-Fed module turns existing principals into a ClaimsPrincipal (like it did with the FormsIdentity), it also checks for RolePrincipal (which is the principal type created by role manager), and turns the roles in role claims. Nice! But as you can see in the last scenario above, this might result in unnecessary work, so I would rather recommend consolidating all role work (and other claims transformations) into the ClaimsAuthenticationManager. In there you can check for the authentication type of the incoming principal and act accordingly. HTH

  • Capturing stdout from an imported module in wxpython and sending it to a textctrl, without blocking the GUI

    - by splafe
    There are alot of very similar questions to this but I can't find one that applies specifically to what I'm trying to do. I have a simulation (written in SimPy) that I'm writing a GUI for, the main output of the simulation is text - to the console from 'print' statements. Now, I thought the simplest way would be to create a seperate module GUI.py, and import my simulation program into it: import osi_model I want all the print statements to be captured by the GUI and appear inside a Textctrl, which there's countless examples of on here, along these lines: class MyFrame(wx.Frame): def __init__(self, *args, **kwds): <general frame initialisation stuff..> redir=RedirectText(self.txtCtrl_1) sys.stdout=redir class RedirectText: def __init__(self,aWxTextCtrl): self.out=aWxTextCtrl def write(self,string): self.out.WriteText(string) I am also starting my simulation from a 'Go' button: def go_btn_click(self, event): print 'GO' self.RT = threading.Thread(target=osi_model.RunThis()) self.RT.start() This all works fine, and the output from the simulation module is captured by the TextCtrl, except the GUI locks up and becomes unresponsive - I still need it to be accessible (at the very minimum to have a 'Stop' button). I'm not sure if this is a botched attempt at creating a new thread that I've done here, but I assume a new thread will be needed at some stage in this process. People suggest using wx.CallAfter, but I'm not sure how to go about this considering the imported module doesn't know about wx, and also I can't realistically go through the entire simulation architecture and change all the print statements to wx.CallAfter, and any attempt to capture the shell from inside the imported simulation program leads to the program crashing. Does anybody have any ideas about how I can best achieve this? So all I really need is for all console text to be captured by a TextCtrl while the GUI remains responsive, and all text is solely coming from an imported module. (Also, secondary question regarding a Stop button - is it bad form to just kill the simulation thread?). Thanks, Duncan

  • j_security_check to SSO in different module under Oracle App Server?

    - by thebearinboulder
    I have an existing j2ee application running on Oracle App Server. It is targeted towards paying customers so the content is secured and a SSO module properly intercepts all requests for secured content. Now the company is adding a unbranded public-facing module with a number of unsecured pages. At one point the user is expected to register for a free account and log in to proceed further. Think doctors adding a public-facing site with information for potential patients, or lawyers adding a public-facing site with information for potential clients. There's some information on the session and the usual approach would be to authenticate the user, persist the session information using the now-known user id, invalidate the existing session (to prevent certain types of attacks), the reload the session information before returning to the user. I can't just persist it under the session id since that's about to change. The glitch is that the existing application already has an SSO module and I get a 404 error every time I try to direct to j_security_check. I've tried that, /sso/j_security_check, even http://localhost/sso/j_security_check, all without success. I noticed that an earlier question said that tomcat requires access to a secured page before j_security_check is even visible. I don't know if that's the case with Oracle AS. Ideas? Or is the best approach to continue arguing that we have a different user base so it would be better to handle authentication in our own module anyway?

  • Zend Framework - How do make a hierarchy without it being a module?

    - by Josh
    Here is my specific issue. I want to make an api level which then under that you can select which method you will use. For example: test.com/api/rest test.com/api/xmlprc Currently I have api mapping to a module directory. I then setup a route to make it a rest route. test.com/api is a rest route, but I would rather have it be test.com/api/rest. This would allow me later to add others. In Bootstrap.php: $front = Zend_Controller_Front::getInstance(); $router = $front->getRouter(); $route = new Zend_Controller_Router_Route( 'api/:module/:controller/:id/*', array('module' =>'default') ); $router-addRoute('api', $route); $restRoute = new Zend_Rest_Route($front, array(), array( 'rest' )); $router-addRoute('rest', $restRoute); return $router; In application.ini: resources.frontController.moduleDirectory = APPLICATION_PATH "/modules" I know it will involve routes, but sometimes I find the Zend Framework documentation to be a little hard to follow. When I go to test.com/rest/controller/ it works how it should, but if I go to test.com/api/rest/ it tells me that my module is api and controller is rest.

  • How can I use io.StringIO() with the csv module?

    - by Tim Pietzcker
    I tried to backport a Python 3 program to 2.7, and I'm stuck with a strange problem: >>> import io >>> import csv >>> output = io.StringIO() >>> output.write("Hello!") # Fail: io.StringIO expects Unicode Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unicode argument expected, got 'str' >>> output.write(u"Hello!") # This works as expected. 6L >>> writer = csv.writer(output) # Now let's try this with the csv module: >>> csvdata = [u"Hello", u"Goodbye"] # Look ma, all Unicode! (?) >>> writer.writerow(csvdata) # Sadly, no. Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unicode argument expected, got 'str' According to the docs, io.StringIO() returns an in-memory stream for Unicode text. It works correctly when I try and feed it a Unicode string manually. Why does it fail in conjunction with the csv module, even if all the strings being written are Unicode strings? Where does the str come from that causes the Exception? (I do know that I can use StringIO.StringIO() instead, but I'm wondering what's wrong with io.StringIO() in this scenario)

The problem is that I can't reset this module to its manufacture settings and I can't connect to this module via serial port to configure it with some wire or cable. But I'm sure that my module is trying to connect my access point but with wrong network key ( because in logs of my access point I can see my module that trying to connect but it can't ) So, I wonder to know is there any way to create or configure a network (using some access point or something else) based on WPA2 Personal security that accepts any WPA2-PSK passwords ? Or is there any other solution for this problem ? If no, is there anyway to see what password this module using to connect to that network ? ( If yes, then I can change password of my network to that password and access to this module's admin panel ) I tried create an open network ( without any security key ) but my module just searches for WPA2 based networks ( I think ).

    When X.org boots up, Synaptics touchpad works well. But when I remove the module it falls back to /dev/input/mice and don't use normal driver even when touchpad is available again. Xorg.0.log: ... (II) XINPUT: Adding extended input device "Synaptics Touchpad" (type: TOUCHPAD) (--) Synaptics Touchpad: touchpad found # { rmmod psmouse && echo mem /sys/power/state && modprobe psmouse; } (WW) : No Device specified, looking for one... (II) : Setting Device option to "/dev/input/mice" ... How to tell X.org to try it's InputDevice again (without restarting X server)? P.S. rmmod psmouse is needed to prevent crashing of Acer Extensa 5220 when resuming from suspend-to-ram. Update: Found answer myself: Doing xinput set-int-prop "Synaptics Touchpad" "Device Enabled" 8 1 after reloading the kernel module reloads touchpad. Now suspend-to-ram works OK.
